Re: [iText-questions] modify pdf objects with iText

Thank you very mutch for your answer, that's just what I was looking for. But I've a problem with the line:

 if (dict.getType() == PdfName.FILESPEC) {

the Visual Studio return me that error:
'iTextSharp.text.pdf.PdfDictionary'does


          not contain a
          definition of 'getType' and found no extension method 'getType' accepting a first argument of type'iTextSharp.text.pdf.PdfDictionary' (are

          you missing a directive use or an
          assembly reference?)

    

    I did it in vb.net and in c# and I've the same error. 

    

    The rest of the code works perfectly and does what I need.

        

        There may be differences between iText or iTextSharp?
          or  is not right this line?

          

          I'm using iTextSharp 5.0.6 and VS 2008.

      Specifically, the manipulatePdf function: 
  
        PdfDictionary action = ""
        PdfDictionary f = action.getAsDict(PdfName.F);
        f.put(PdfName.F, new
PdfString("http://itextpdf.com:8080/book/request");

Your code is presumably looping through every object in the PDF, looking
for one that contains the string "/Filespec".  That could work, but you
don't know if the file specification is its own object, or part of
something else.  File speicifcation dictionaries are not required to be
top level objects, so just because you see /FileSpec doesn't mean you
know now to it out of your "obj".

You say this is a link in a PDF collection.  In THIS PARTICULAR CASE, it
sounds like you can safely use that technique.  As soon as your PDFs
start coming from different sources, or the file isn't part of a
collection, all bets are off.

To generalize your code a little more, I suggest the following... You'll
have to forgive my Java, I no speaky VB.net.

   if (obj.isDict()) {
     PdfDictionary dict = (PdfDictionary) obj;
     if (dict.getType() == PdfName.FILESPEC) {
       PdfString oldSpec = dict.getAsString(PdfName.F);
       String specStr = oldSpec.toString();
       String newSpecStr = modifySpecStrSomehow(specStr);
       dict.put(PdfName.F, new PdfString( newSpecStr );
     }
   }
